DETAIL DESCRIPTION OF PREFERRED EMBODIMENT

[0012] Referring to FIG. 1, the folding handle bar for bicycle comprises a folding handle bar 1 including a handle bar 10, a stem 20 and control screw device 30, and the handle bar 10 includes a first handle bar 11 and a second handle bar 12, both of them having same structure. The side of first handle bar 11 locates a handle grip 111 (refer to FIG. 3) and the other side installed a handle holder 13 which locates two rooms 131,132 at each side, rooms 131,132 connected by a path 133 at center. Meanwhile, the rooms 131,132 could replace a hollow body of handle holder 13. There is a fastening housing 14 and a pad 15 to locate each room of handle holder 13 wherein the pad 15 is a plastic friction lining and could replace a bearing. Both the fastening housing 14 and the pad 15 are located holes 141,151, and a screw blot 16 goes through the holes 141,151 and the path 133. In addition, the side of handle holder 13 installed a connecting member 17 locating a hole 171 and a gap 172, and the hole 171 located one of handle bars and had a pin 18 locating a hole 181 with screw thread insert where the pin 18 connected the connecting members with holes 171,172 and the hole 181 set the gap 172 of the connecting members 17. The stem 20 coupled to the handle bar 10 which top of it couples to a bracket 21 installed two columns 22 in order to couple to the first and second handle bar 11,12 that have a hole 221 with screw thread insert. Also, the control screw device 30 includes a screw cap 31, a fastening screw part 32 and a screw rod part 33, and the diameter of the fastening screw part 32 is bigger than the gap 172 between the connecting members 17. The diameter of the screw rod part 33 is smaller than the fastening screw part 32 and the gap 172 between the connecting members 17. The screw cap 31 locates a screw thread on it for hand to fasten or release. The side of screw rod part 33 has screw threads for coupling to the hole 181 of pin 18.

[0013] Referring to FIG. 2, the folding handle bar for bicycle takes the columns 22 of stem 20 inserting the lower rooms 132 of first, second handle bar 11,12, And, the screw blot 16 through the fastening housing 14, the pad 15 and the path 133 fastens with the holes 221 of the columns 22. Finally, the screw rod part 33 of control screw device 30 couples to the hole 181 of pin 18 via the gap 172 of connecting members 17 of first handle bar 11 and fastens on the connecting member 17 of second handle bar 12 with the fastening screw part 32.

[0014] Referring to FIGS. 4 and 5, the release-operation folding handle bar releases the control screw device, coupled to the pin 18, in order to take the fastening screw part off the connecting members 17 of the second handle bar 12, and moved the control screw device to the first handle bar 11. Then, the first and second handle bar 11, 12 fold to the collocation by moving in horizon.
